ff7301d6a8 ICE extraction overhaul: API discovery + aging report + historical backfill 
- Replace brittle ICE_STOCKS_URL env var with API-based URL discovery via
  the private ICE Report Center JSON API (no auth required)
- Add rolling CSV → XLS fallback in extract_ice_stocks() using
  find_latest_report() from ice_api.py
- Add ice_api.py: fetch_report_listings(), find_latest_report() with
  pagination up to MAX_API_PAGES
- Add xls_parse.py: detect_file_format() (magic bytes), xls_to_rows()
  using xlrd for OLE2/BIFF XLS files
- Add extract_ice_aging(): monthly certified stock aging report by
  age bucket × port → ice_aging/ landing dir
- Add extract_ice_historical(): 30-year EOM by-port stocks from static
  ICE URL → ice_stocks_by_port/ landing dir
- Add xlrd>=2.0.1 (parse XLS), xlwt>=1.3.0 (dev, test fixtures)
- Add SQLMesh raw + foundation models for both new datasets
- Add ice_aging_glob(), ice_stocks_by_port_glob() macros
- Add extract_ice_aging + extract_ice_historical pipeline entries
- Add 12 unit tests (format detection, XLS roundtrip, API mock, CSV output)

Seed files (data/landing/ice_aging/seed/ and ice_stocks_by_port/seed/)
must be created locally — data/ is gitignored.

67c048485b Add Phase 1A-C + ICE warehouse stocks: prices, methodology, pipeline automation 
Phase 1A — KC=F Coffee Futures Prices:
- New extract/coffee_prices/ package (yfinance): downloads KC=F daily OHLCV,
  stores as gzip CSV with SHA256-based idempotency
- SQLMesh models: raw/coffee_prices → foundation/fct_coffee_prices →
  serving/coffee_prices (with 20d/50d SMA, 52-week high/low, daily return %)
- Dashboard: 4 metric cards + dual-line chart (close, 20d MA, 50d MA)
- API: GET /commodities/<ticker>/prices

Phase 1B — Data Methodology Page:
- New /methodology route with full-page template (base.html)
- 6 anchored sections: USDA PSD, CFTC COT, KC=F price, ICE warehouse stocks,
  data quality model, update schedule table
- "Methodology" link added to marketing footer

Phase 1C — Automated Pipeline:
- supervisor.sh updated: runs extract_cot, extract_prices, extract_ice in
  sequence before transform
- Webhook failure alerting via ALERT_WEBHOOK_URL env var (ntfy/Slack/Telegram)

ICE Warehouse Stocks:
- New extract/ice_stocks/ package (niquests): normalizes ICE Report Center CSV
  to canonical schema, hash-based idempotency, soft-fail on 404 with guidance
- SQLMesh models: raw/ice_warehouse_stocks → foundation/fct_ice_warehouse_stocks
  → serving/ice_warehouse_stocks (30d avg, WoW change, 52w drawdown)
- Dashboard: 4 metric cards + line chart (certified bags + 30d avg)
- API: GET /commodities/<code>/stocks

Foundation:
- dim_commodity: added ticker (KC=F) and ice_stock_report_code (COFFEE-C) columns
- macros/__init__.py: added prices_glob() and ice_stocks_glob()
- pipelines.py: added extract_prices and extract_ice entries
